Methods and apparatuses for making color filter, liquid crystal device, and electro-luminescent device and inkjet head controller, and a method for discharging material, and an apparatus for discharging material

摘要

A method for making a color filter having a plurality of filter elements aligned in a dot-matrix on a substrate is provided. The method has a first-scanning step of moving the inkjet head having a nozzle line including a plurality of nozzles relative to the substrate while selectively discharging a filter material from the plurality of nozzles so as to form filter elements on filter element forming regions of the substrate and a second-scanning step of moving the inkjet head by a second-scanning distance delta in a second-scanning direction. The plurality of nozzles are divided into a plurality of groups and the first-scanning step and the second-scanning step are repeated so that all the nozzle groups scan the same section of the substrate. <IMAGE>
